REMOVABLE FOLDING SEAT Filed April 50, 1929 y awn Patented Apr. 29, 1930UNITED STATES PATENT OFFICE- JOI-IN F. HOLLIIDAY, OF \VASHINGTON,INDIANA, ASSIGNOR T0 HINCHER MANUFAC- TURING COIVIPANY, OF WASHINGTON,INDIANA, A CORPORATION OF INDIANA REMOVABLE FOLDING SEAT Applicationfiled April 30,

The object of this invention is to provide a removable seat with aback-rest to be used on. boat seats and on bleacher board seats at ballgames, circuses and the like, which can be easily and quickly placed foruse or removed for transportation orv storage, and in which the seat isfoldable for greater compactness.

Another object is to provide a well braced and durable device which willbe cheap to manufacture I accomplish the above, and other objects whichwill hereinafter appear, by the means illustrated in the accompanyingdrawing, in which Fig. 1, is a perspective view of a bleacher board withmy invention operatively applied.

Fig. 2, is a side elevation of my invention removed from the bleacherboard and with the hack raised.

Fig. 3, is a like View, showing the hinge between the seat and back andadjacent parts in vertical section and also showing a modified form ofseat clamping spring.

Fig. 4, is a fragment in rear elevation,

' showing a seat and back and a seat clamp on one side of the seat.

Fig. 5, is an under side plan view of the seat shown in Fig. 3, with theback of the seat swung out to the position of use, and;

Fig. 6, is a section on the line 66 of Fig. 4, on a larger scale, andshowing a fragment of the top of the seat.

Like characters of reference indicate like parts in the several views ofthe drawing.

The plain seat board 7 may be a bleacher board, boat seat, or otheruncomfortable seat without a back-rest, such as are in common use, andupon which my invention is supported and to which it is removablyattached.

The seat portion .of my device is composed of a frame having a pair ofside members 8, 8, which are connected at their front and back ends bycross members 9, 9. The two side members are longitudinally grooved ontheir inner edges and receive therein the ends of slats 10 which fillthe space between the four frame members, and also the reduced ortongued ends of the cross members 9, 9, which may be tacked or gluedtherein, or both tacked and glued.

may be variously formed integrally but for economy of material I preferto make them out of strap metal having ends lapped over and spot weldedto the strap 11 For a major portion of the length of strap 11, at itsmiddle, it is bowed away from the seat frame as shown at 14, to secure aresiliency which will be more comfortable to the person occupying theseat and which will normally tilt the rear of the seat up and whichcauses the clamp hook 12 to more closelv engage the'seat board.

In the modification shown in Figs. 3 and 5, the strap 11 is in twoparts, 15 and 16, at the middle bow, in order the more fully to developthe spring action above referred to.

The strap 11 is secured to the frame member 8 by a screw at the frontend of the bow 14 (or 15and 16) and by a rivet 17 near the rear end.

A back comprising a pair of standards 18, 18, and cross members 19, 19,is hinged at the front and lower ends of the standards, to the uppersides of the frame members 8, within shallow grooves 20, 20, formed inthe frame members, by means of leaf hinges. The leaf of each hingecontacting a standard is secured by a rivet 21 which passes also throughthe standard to keep the end of the latter from splitting, and the outerend of the leaf terminates with a barb 22 which is driven into thestandard to keep the leaf from ro-, tating on the rivet. The other leaf23 of each standard is of a width to make a close fit in its groove 20,where it is secured by the rivet 17, which passes through the framemember of the seat and also through the strap 11, thereby serving thedouble purpose of securing the hinge and the strap. The outer end ofleaf 23 makes a close fit in the correspondingly shaped end of thegroove 20 to prevent play. This end may be half formed as shown or anydesired shape.

The ends of the hooks 12 are curved outwardly to make them easier of aplioation to the seat and the straps 11 are pre erably bent down at 24 tomake cont-acting faces level with the lateralextensions 13,

From the foregoing description it will be obvious that a useful andcomfortable folding seat has been produced capable of wide and generaluse and adapted to be collapsed in a compact structure occupying butlittle 15 space.

It will, of course, be understood that various changes may be made inthe form, details, proportions and arrangements of parts withoutdeparting from the spirit and scope of my invention. I

What I claim, is- 1. The combination with a chair-seat and a whair-backhinged thereto, of securing means comprising resilient metal strapssecured to the seat having front ends bent to form hooks and otherportions bowed downwardly to cushion the seat and increase the holdingtension on the hooks.-

2. The combination with a chair-seat and a chair-back hinged thereto, ofsecuring means comprising resilient metal straps secured to the underside of the seat having front ends bent to form hooks and other portionsoverlapped and bowed downwardly to as cushion the seat and increase theholding ten sion on the hooks. 1 3. The combination with a chair-seat,coming standards entering the channels, leaf hinges securing the back ofthe seat having leaves entering the channels and held from lateralmovement by the sides of the channels, means securing the straps to theframe comprising rivets which also secure the hinges to the seat, saidstraps having front-end hooks and bowed portions to cushion the seat andincrease the holding tension on the hooks.

6. The combination with a chair-seat comprising frame members joined attheir intersections, of securing means consisting of resilient metalstraps secured to the frame and having lateral extensions overlappingthe corner joints of the frame, said frame having channels in its topsurface, a chair-back having standards entering the channels,leafhinges, securing the back of the seat having leaves enteringthechannels and held from lateral movement by the sides of the channels,means securing the straps to the frame comprising rivets which alsosecure the hinges to the seat, said straps having front-end hooks andbowed portions to cushion the seat and increase the holding tension onthe hooks, said rivets being passed through the rear ends of the straps,the frame, and the hinge leaves and having heads spunv over onto thestrap and leaves to compressively engage the frame therebetween.
